You spend an hour instructing someone on how to perform a trick of the trade that you know. The trick must be no higher than fourth tier. For one hour after you teach them, the student can perform that trick of the trade as if it were natural for them. They must pay the Might, Speed, or Intellect cost (if any) to use that trick. The student must be able to understand your instructions. In addition to the normal options for using Effort, you can choose to use Effort to increase how long the student can use the trick or to teach additional students at the same time; each level of Effort used in this way increases the duration by one hour or the number of students by one.
